A 'miracle trial' claims that severe autism can be reversed and symptoms can be reduced if a child is treated regularly from a young age.

The unprecedented findings follow a two-year study involving two twin girls in the United States who were diagnosed with autism at 20-months-old. 

As a part of the pioneering research, the programme was designed to help both girls thrive and flourish.

Scientists are claiming the programme was a success with the twins seeing 'dramatic' changes in their symptoms. 

One of the girls, named Twin P, saw her score on the Autism Treatment Evaluation Checklist dramatically drop from 43 out of 180 in March 2022 to four by October 2023.
